Summary

    A vulnerability in the web-based management interface of Cisco Small
    Business 300 Series Managed Switches could allow an unauthenticated, remote
    attacker to conduct a cross-site scripting (XSS) attack against a user of
    the interface of an affected system.

    The vulnerability exists because the affected management interface performs
    insufficient validation of user-supplied input. An attacker could exploit
    this vulnerability by persuading a user of the interface to click a
    malicious link. A successful exploit could allow the attacker to execute
    arbitrary script code in the context of the affected interface or allow the
    attacker to access sensitive, browser-based information.

    There are no workarounds that address this vulnerability.
